Cutting Titanium Sheet Metal

Because it is a reactive metal it changes its chemical properties when exposed to heat.

Cutting titanium sheet metal.

The wavelength of the optical fiber laser is 1 06μm is more easily absorbed by the metal material compared with the wavelength of co 2 which is 10 6 μm and is especially beneficial for sheet metal cutting. In the video below you can see a cosen ah320 horizontal band saw being used to cut a block of titanium. Laser cutting 1 16 stainless steel with oxygen assist gas duration. The sheet cutting speed is 2 4 times of co 2.

Cutting titanium is not an easy task. A sharp cutting edge minimizes cutting forces in titanium but the cutting edge also needs to be strong enough to resist cutting pressure. A secondary relief tool design in which the first positive area of the cutting edge resists forces after which the second area falls away to increase clearance accomplishes both these objectives see. That means it s not possible to cut titanium using traditional methods without changing its chemical composition.

Because it is one of the most resilient metals in the world cutting titanium is no easy task. Laser cutting titanium thick titanium materials such as plates or reinforced sheets are typically cut with co2 lasers because they have higher power capacity than other laser models. It s true that improvements in fiber lasers have resulted in a wider range of options for laser metal cutting including copper brass titanium and other alloys that weren t ideal for co 2. Laser cutting 5mm sheet metal titanium grade 5 duration.

Using a carbide tipped band saw blade not only allows for the successful cutting of titanium alloys but it simultaneously offers longer blade life and faster cutting as well. With the investment in our new ventis fibre laser we can now cut titanium sheet up to 8mm thick with precision and ease. Titanium is known for its strength corrosion protection and light weight composition but because of a low melting point it is impossible to cut using traditional co2 laser technology. Since titanium alloys are a stronger and harder material they pose a unique cutting challenge best solved by carbide blades.
